One step forward, and 0.9 steps back

I'm trying to run a very simple (my first) Android app in an emulator I've set up, but my app doesn't display within the emulator. I'm expecting to see (code below) a TextView with some Text assigned to it.

All I see is a black "honeycomb" background in the emulator (which looks like a "DOS box" or Command prompt) with the time (5 hours in the future), date, and "Charging (50%)"

I'm using an AVD set up to use a version 3.2 emulator. I've got that (Andorid 3.2 SDK) and Java 7 installed.

You will also want to change your code. Right now you're setting the ContentView to tv, and then you're telling the activity to display the (presumable empty) main.xml instead. You should probably acquaint yourself with Android's XML-based UIs too, because in my experience trying to set up the UI in code doesn't get your very far in Android.
